Qumulo Storage Array
In 2020 we implemented an all-flash based Qumulo Storage array with capacity of 2.29 PB of raw disk. Our leading requirement was fast, very fast. The old array had plenty of capacity but would make for slow calculations due to contention for the slower disk drives. So the new array was no longer a bottle-neck for compute, and providing faster compute increases the efficiency of the supercomputers. The trade-off is that it is very expensive and we do not currently have an option for renting storage by the TeraByte.
We have developed a plan for Tier 2 storage which will be where research data is stored that is not in active compute.
